An afterparty, after-party, or after party is a gathering that occurs after a party, a music concert, a premiere or the closure of a nightclub. An afterparty may provide additional social opportunities for people who do not want to return to their respective homes.The main purpose of the afterparty is to provide a relaxing environment, as compared to the earlier venue, where the atmosphere is usually more frenetic. During an afterparty people often sit down, relax, and chat freely, meet new people in a more controlled setting. If the original party was one that continued until late at night, the afterparty will often include a morning snack, which usually counts as breakfast.
The Latin word repotia describes a concept similar to an afterparty, literally translated as "a second round of drinks" and translated as "party that follows the original entertainment" or "discourse celebrating a wedding feast."
